5 April Is Coming: What UK Businesses Must Do Now 2026

March 4, 2026

Introduction

As the 5th of April gets closer, businesses in the United Kingdom are getting ready for a financial deadline. This is the end of the 2025 to 2026 tax year. For people who own businesses in Scotland and the rest of the United Kingdom, this is their chance to look at their accounts and make sure they are paying the right amount of tax. They also need to make sure they are doing everything the HMRC says they should be doing before the new tax year starts on the 6th of April 2026.

At A2Z Accounting Solutions, we help companies and sole traders and partnerships and small businesses that are growing. We make sure they are ready for the deadline. We do this before the deadline, not after it. We work with businesses like these to get everything sorted out on time.

Here’s what UK businesses must do now to avoid penalties, reduce tax liabilities and start the 2026/27 tax year strong.

1. Review Your Year-End Tax Position

Before April 5 2026, businesses should look at:

• Profit levels for the year
• Corporation Tax exposure
• Director’s salary and dividend payments
• Outstanding expenses
• Allowable deductions
• Capital expenditure
• VAT liabilities

Waiting until after the tax year ends removes many tax-planning opportunities. Early action allows for legitimate strategies to reduce Corporation Tax and personal tax liabilities.

2. Use Remaining Allowances Before 5 April

The tax year deadline means certain allowances reset on 6 April. If unused, they are lost.

Key allowances to review:

Annual Investment Allowance (AIA)
Businesses can get 100 percent tax relief, on equipment purchases that qualify. If you plan to buy machinery IT gear or business tools think about doing it before the year ends.

Director’s Salary & Dividend Planning
Ensure directors have used their personal allowance and dividend allowance efficiently.

Pension Contributions
Company pension contributions reduce taxable profits. Making contributions before 5 April can lower your tax bill.

ISA Allowance
For business owners drawing income, the unused ISA allowance (£20,000 per person) expires at the year-end.

3. Check Your VAT Position

VAT compliance remains one of HMRC’s key enforcement areas for 2026.

Before 5 April:

• Review quarterly VAT returns
• Ensure Making Tax Digital (MTD) compliance
• Check VAT on imports and overseas sales
• Confirm the correct VAT treatment of zero-rated or reduced-rated goods
• Reconcile VAT control accounts

Errors in VAT submissions can lead to penalty points and fines under HMRC’s updated late submission regime.

4. Prepare for Corporation Tax

Limited companies must calculate Corporation Tax based on profits for the financial year. With Corporation Tax rates remaining at up to 25% for higher profit bands in 2026, planning is essential.

Before year-end:

• Review accruals and prepayments
• Confirm allowable business expenses
• Consider timing of large purchases
• Assess R&D tax relief eligibility
• Review director loan accounts

Early preparation ensures accurate filings and prevents cash flow surprises later.

5. Payroll & Pension Compliance

As the tax year ends, payroll processes must be checked carefully.

Businesses should:

• Confirm PAYE submissions are up to date
• Review benefits-in-kind reporting
• Ensure NEST or auto-enrolment pension compliance
• Prepare P60s and P11Ds where required
• Verify holiday pay calculations

Payroll mistakes often make HMRC check if companies are following the rules. This happens a lot in hospitality and construction.

6. Review Cash Flow & Financial Forecasting

The end of the tax year is a time to review how the company has performed financially and set realistic goals for the tax year 2026/27. We should review the performance and then set targets for the tax year 2026/27. This will help us plan for the future.

Ask:

• Is your cash flow tight at times of the year?
• Are overheads increasing?
• Is cash flow tight at certain points of the year?
• Do you need funding or restructuring?

Management accounts are really helpful. They give you an idea of what is going on with your business. This helps companies in Scotland and the UK make choices about what to do next with their business.

7. Sole Traders & Self-Employed: Act Before 5 April

If you are a sole trader or self-employed professional:

• Finalise expense claims
• Review use of home office claims
• Consider equipment purchases
• Check CIS deductions
• Ensure income is fully recorded

Self Assessment tax planning before 5 April can help reduce tax liabilities due in January 2027.

8. Avoid Last-Minute HMRC Stress

Every year, many businesses wait until after 5 April to start reviewing their finances. By then, planning options are limited.

Working with A2Z Accounting Solutions allows you to:

• Identify tax-saving opportunities
• Avoid missed allowances
• Ensure compliance with HMRC
• Improve profitability
• Start the new tax year confidently

9. Prepare for 2026 Changes

Looking ahead, UK businesses must also prepare for:

• Expanded Making Tax Digital requirements
• Increased digital reporting
• E-invoicing developments
• Ongoing scrutiny around VAT and payroll
• Changes in Scottish tax bands, where applicable

Businesses operating in Scotland should be particularly aware of devolved income tax rates that may differ from the rest of the UK.

Why Planning Before 5 April Matters

Tax planning is not about avoidance — it’s about efficiency and compliance. The right preparation can:

• Reduce tax legally
• Protect cash flow
• Improve financial clarity
• Avoid penalties
• Strengthen business stability

The days before 5 April are your final window to act.
